Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit b6e95dc063a2, unchanged since the check below.

SECRETS_PATH_UNCONFIRMED PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ

Why this grade

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    skills/collaborating-with-claude/scripts/claude_bridge.py, line 457 if args.bare and not os.environ.get("ANTHROPIC_API_KEY"):

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    skills/collaborating-with-antigravity/scripts/agy_bridge.py, line 63 proc = subprocess.run(

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    skills/collaborating-with-antigravity/references/agy-cli.md, line 11 curl -fsSL https://antigravity.google/cli/install.sh | bash # installs `agy` to ~/.local/bin

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    skills/collaborating-with-claude/scripts/claude_bridge.py, line 457 if args.bare and not os.environ.get("ANTHROPIC_API_KEY"):

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
